On November 14, 2012, Israel declared war on Gaza by tweet.

Gaza Strip

When the Israeli Defense Forces (@IDFSpokesperson) tweet-announced its November 2012 “Pillar of Defense” assault, it added: “We recommend that no Hamas operative… show their faces above ground in the days ahead.” The military wing of Gaza’s Hamas government (@AlqassamBrigade) replied: “You Opened Hell Gates on Yourselves.” As missiles crashed into Gaza and mortars fell on Israel, Twitter users around the world commented under their chosen hashtag of allegiance: #PillarofDefense versus #GazaUnderAttack.
